yeah the right thumb is a "one-shot" key to go to the second layer. So you press it, and then only whatever key you press next is on the second layer. So you're always on the fist layer unless you just pressed that key.

It does end up being (slightly) more keypresses, but it's built on the idea that 1.) two comfortable keypresses are easier than one uncomfortable keypress and 2.) our thumbs are already absurdly under-utilized on current keyboards.
